摘要
本文在AutoCAD平台下,以钻孔信息、剖面图和空间离散点为基础数据,采用顾及台阶属性的Delaunay三角网凸包算法建立界面模型,通过面域拉伸和实体布尔运算等方法生成三维实体模型。研究结果表明,该方法不仅能达到逼真的三维动态效果,而且对于矿岩量的计算更为准确方便。研究结论初步突破了露天矿算量的传统方法,有助于露天矿的日常生产和管理。
By using drill hole information, section chart and discrete space point as fundamental data, the author designed a general process of 3D geological modeling based on AutoCAD. The modeling method firstly established face model by using a considering bench attribute Delaunay TIN convex hull algorithm,then sets up the mining solid model by strengthening region and using solid Boolean operation. The results show that, this method provides not only reality - dynamic effect, but also gives a more accurate result in calculating the volume of mine. The conclusion of this study preliminary breakthroughs traditional calculating volume method in surface mine,and also it＇s helpful to surface mining and management.
